Sure, you'll never get rid of all misleading information; however, without advertising the volume of shit will reduce radically, as much of the modern internet is built around profiteering and get rich quick schemes (influencers), which breed swathes of hopeful emulators.

I think most sensible people are quite competent at ignoring the bullshit, so I would love it if there was less bullshit to wade through to get to the nuggets of useful information which are out there. For those too stupid to look past misleading information, there's no helping them anyway.
